Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
Oppositional Defiant Disorder01:30

Oppositional Defiant Disorder

A persistent pattern of angry or irritable mood, defiant behavior, or vindictiveness characterizes Oppositional Defiant Disorder (ODD). Symptoms must occur over at least six months, involve interactions with individuals beyond siblings, and meet specific diagnostic criteria to be clinically significant. The disorder affects emotional regulation, social interactions, and behavior, often manifesting early in life and influencing long-term development and functioning.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Conduct Disorder01:28

Conduct Disorder

Conduct disorder is a complex mental health diagnosis characterized by a repetitive and persistent pattern of behavior that violates societal norms, the rights of others, or age-appropriate rules. The diagnostic criteria for conduct disorder require the presence of at least three problematic behaviors within the past 12 months, with at least one occurring in the past six months. These behaviors are grouped into four categories: aggression toward people and animals; destruction of property;...
Alzheimer's Disease: Overview01:26

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...
Obsessive-Compulsive Disorder01:28

Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by recurrent obsessions, compulsions, or both, which consume significant time and interfere with daily functioning. Obsessions involve persistent, intrusive, and unwanted thoughts, images, or urges that evoke anxiety. Common examples include irrational fears of contamination or harm. Compulsions are repetitive behaviors or mental acts performed to reduce the anxiety caused by obsessions. For instance, individuals...

Summary
This summary is machine-generated.

Executive function (EF) deficits and delay aversion (DAv) are linked to attention deficit hyperactivity disorder (ADHD), but are not required for diagnosis. These factors may help identify ADHD subtypes.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Developmental Psychology

Background:

  • Attention deficit hyperactivity disorder (ADHD) diagnosis relies on specific criteria.
  • Executive function (EF) deficits and delay aversion (DAv) are frequently observed in individuals with ADHD.
  • The precise role of EF deficits and DAv in ADHD diagnosis and classification remains under investigation.

Purpose of the Study:

  • To critically evaluate the role of executive function (EF) deficits and delay aversion (DAv) in the diagnosis of attention deficit hyperactivity disorder (ADHD).
  • To explore the potential of EF deficits and DAv in understanding ADHD heterogeneity and refining its nosology.

Main Methods:

  • The study is based on an empirical review of existing literature.
  • Analysis focuses on the relationship between EF deficits, DAv, and ADHD diagnostic criteria.
  • Conceptual examination of how these constructs relate to ADHD subtypes.

Main Results:

  • EF deficits and DAv are clearly implicated in ADHD.
  • Neither EF deficits nor DAv are necessary or specific to ADHD.
  • EF deficits and DAv are dissociable constructs, potentially identifying distinct ADHD subsamples.

Conclusions:

  • EF deficits and DAv currently offer limited diagnostic value for ADHD as conventionally defined.
  • These constructs may be crucial for partitioning ADHD heterogeneity.
  • Further research into EF deficits and DAv could lead to a refined nosology of ADHD.
